Abahanga mu bya siyansi bo mu Budage no mu Buholandi barimo gukora ubushakashatsi ku bidukikije bishyaPLAibikoresho. Intego ni uguteza imbere ibikoresho birambye byo gukoresha mu ikoranabuhanga nk'amatara y'imodoka, lenses, plastiki igarura urumuri cyangwa ubuyobozi bw'urumuri. Kugeza ubu, ibi bikoresho muri rusange bikorwa muri polycarbonate cyangwa PMMA.
Abahanga mu bya siyansi barashaka kubona pulasitiki ikoze muri bio-based to maker to car headlamps. Byagaragaye ko aside polylactic ari igikoresho cyiza.
Binyuze muri ubu buryo, abahanga mu bya siyansi bakemuye ibibazo byinshi bya pulasitiki gakondo: icya mbere, kwibanda ku mutungo ushobora kongera gukoreshwa bishobora kugabanya neza igitutu giterwa na peteroli ku nganda za pulasitiki; icya kabiri, bishobora kugabanya imyuka ihumanya ikirere ya karuboni; icya gatatu, ibi bikubiyemo gusuzuma ubuzima bwose bw'ibintu.
“Aside polylactic ntabwo ifite ibyiza gusa mu bijyanye no kuramba, ahubwo inafite imiterere myiza cyane y’urumuri kandi ishobora gukoreshwa mu miraba igaragara ya electromagnetic,” ibi ni ibyavuzwe na Dr. Klaus Huber, umwarimu muri Kaminuza ya Paderborn mu Budage.
Muri iki gihe, kimwe mu bibazo abahanga mu bya siyansi barimo gutsinda ni ikoreshwa rya aside polylactic mu bijyanye na LED. LED izwi nk'isoko y'urumuri ikora neza kandi itangiza ibidukikije. Huber arasobanura ati: "By'umwihariko, igihe kirekire cyane cyo gukora n'imirasire igaragara, nk'urumuri rw'ubururu rw'amatara ya LED, bituma ibikoresho biramba cyane bikenerwa cyane." Iyi niyo mpamvu ibikoresho biramba cyane bigomba gukoreshwa. Ikibazo ni uko: PLA iba yoroshye kuri dogere 60. Ariko, amatara ya LED ashobora kugera ku bushyuhe bugera kuri dogere 80 mu gihe akora.
Indi ngorane ikomeye ni ugukora kristali ya aside polylactic. Aside polylactic ikora kristali ku bushyuhe bwa dogere 60, bigatuma ibintu bihinduka. Abahanga mu bya siyansi bashakaga uburyo bwo kwirinda uku gukora kristali; cyangwa gutuma inzira yo gukora crystali iba igenzurwa neza - kugira ngo ingano ya crystallites yakozwe itagira ingaruka ku mucyo.
Muri laboratwari ya Paderborn, abahanga babanje kugena imiterere ya molekile ya aside polylactic kugira ngo bahindure imiterere y'ikintu, cyane cyane imiterere yacyo yo gushonga no guhinduka kwa kristale. Huber ifite inshingano zo gusesengura uburyo inyongeramusaruro, cyangwa ingufu z'imirasire, zishobora kunoza imiterere y'ibikoresho. Huber yagize ati: “Twubatse sisitemu nto yo gukwirakwiza urumuri rw'imfuruka nto kugira ngo yige uburyo kristu ikora cyangwa ishonga, imikorere igira ingaruka zikomeye ku mikorere y'urumuri.”
Uretse ubumenyi bwa siyansi na tekiniki, uyu mushinga ushobora gutanga inyungu zikomeye mu bukungu nyuma yo gushyirwa mu bikorwa. Itsinda ryiteze gutanga urupapuro rwa mbere rw'ibisubizo byawo bitarenze impera za 2022.
